The data cannot be modeled by a linear equation because the rate of change is not constant. This can be seen in the fact that when you increase x from 1 to 2, you subtract 3 from the y-values. However, as you add 2 more, you continue to subtract 3 from the y-values. If the function were a linear function, we would likely subtract 6 from the y-values, since that would form a constant ratio.

You can even look at the fact that as we increased the x by 4, we continued to decrease the y by 3. This does not form a constant ratio, and is thus the data could not be modeled by a linear function.

$\frac{x}{4000 } = \frac{78}{100}$
78×4000=312000
100×x=100x
312000÷100=3120
3120+4000=7120<----2nd month
7120×0.5=3560<----3rd month
4000<----1st month
4000+3560+7120=14680<----Your answer, this is the total of the three months.

2. Are the expressions -5 + -2 and -5 – 2 equivalent? Why or why not? Explain and show your work.

scoray [572]

Answer:

Yes, the expressions are equivalent.

Step-by-step explanation:

Notice that -2 is defined as in additive inverse of 2, that is, 2 + -2 = 0.

and substracting 2 from 2 is also equal to zero, that is, 2 - 2 = 0.

Thus 2-2 = 2+ -2, implying -2 = + -2. Consequently, -5 + -2 = -5 -2

Before the election, you want to determine the number of possible president/vice-president combinations for the sorority you bel

vichka [17]

Solution: We have to choose two positions president and vice president from eight people. So, we need to use the Permutations formula in order to find the possible number of combinations.

The number of possible combinations is:

8P2 $=\frac{8!}{(8-2)!}$

$=\frac{8\times7\times6\times5\times4\times3\times2\times1}{6\times5\times4\times3\times2\times1}$

$=\frac{40320}{720}$

$=56$

Therefore the possible number of combination to select two positions from 8 people is 56
